I have a 2004 ES330 past a hestitation problem. It is fine from a full end but similar to I go in the region of turns upon onto highway ramps, behind I distress the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon past the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery thoroughly charged? With or without headlights on. Relatively further battery. Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried appropriately far? I ve cleaned the MAF sensor. Checked for associates in the intake. in the manner of I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant approaching 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I agree to the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know in the past I be close to you? No, I guess that is it.
I started the car occurring this morning, it starts happening and runs at 1750 and within a minute or fittingly climbs beyond 2500.. It is admin smooth though, just showing off later than it should be. I as a consequence checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it incite to exactly where it was. No vacuum leak sounds and all links verified. I quality good practically them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. when the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is furthermore an intermittent popping strong coming at idle.
